Pull request overview

This pull request updates the theme's accent color from dark purple/slate blue (rgb(72, 61, 139)) to cyan (rgb(93, 187, 204)), which matches the application's logo. The update also modernizes the design by removing gradient backgrounds in favor of a flat design aesthetic. The changes span the QSS stylesheet template, the generated stylesheet, and the compiled binary resources.

Key changes:

• Replaced primary border color from #483d8b (dark purple) to #5dbbcc (cyan)
• Replaced highlight border color from #5246a0 to #7fd4e0 (lighter cyan)
• Removed all qlineargradient declarations, replacing them with solid colors
• Updated comments to reflect "flat backgrounds" instead of "gradient backgrounds"

This background color should be rgb( 47, 72, 79) instead of rgb( 55, 81, 88) to correctly represent rgba(93, 187, 204, 25%) blended over the background rgb(32, 34, 37).

The calculated RGB value for rgba(93, 187, 204, 25%) blended over the background rgb(32, 34, 37) is incorrect.

Correct calculation:

• Red: 93 × 0.25 + 32 × 0.75 = 23.25 + 24 = 47.25 ≈ 47
• Green: 187 × 0.25 + 34 × 0.75 = 46.75 + 25.5 = 72.25 ≈ 72
• Blue: 204 × 0.25 + 37 × 0.75 = 51 + 27.75 = 78.75 ≈ 79

The value should be rgb( 47, 72, 79) instead of rgb( 55, 81, 88).

This also affects line 410 where this calculated color is used as a background-color.

The layout changes are irrelevant this this PR, I do not want this PR to touch RareStyle. If you want an alternative stylesheet, then create a new one. I don't mind basing it on RareStyle, but I do not want the default style to change at this point.
